Calculation is feasible. By comparison of the pressure wave that MPC turbocharged diesel engine for different loads and different structural parameters of the pressurization system,true religion, according to the calculation model presented in this paper deal with the exhaust pipe when the gas flow, the calculation of pressure waves obtained with the row tracheal pressure wave corresponding to the measured points are in good agreement degrees. Performance parameters from the diesel engines can also be seen in comparison with the measured results of the calculation are in good agreement. Figure 4 Calculation of turbine inlet pressure and the actual swirling shabu (scorpionfish = 40r / s) Figure 5 and the real pipe at the entrance to rinse pressure was calculated (scorpionfish = 30r / s) short, according to the calculation and comparison of test results, both diesel and pressurization system performance parameters, or all points of the pressure wave, which is calculated with the test results are good agreement twist. It shows that the established model is feasible, can reflect the MPcab hide air force within the system and simulates the case of wave mode MPC turbocharged diesel engine turbocharger thermal process. Although the simulation can not accurately reflect the test results, but the results can be used for qualitative analysis, forecasting the performance of MPC turbocharged diesel engine,belstaff italia, and change the program forecasts of the qualitative work of guiding significance. This new model MPC boundary there is further potential for adjustment,uggs bestellen, should be further studied and improved, and hope more models verified. V. CONCLUSIONS By 8V165/155 supercharged diesel engine using MPC and Simulation Study reached the following conclusions: 1. Turbocharged diesel engine used in 8V16s/lss MPC has been successful for the external characteristics of working conditions, Turbocharged diesel engine using MPC in the whole speed range power increased by 44 ~ 48.9kW,christian louboutin pas cher, fuel consumption decreased by 9.4 ~ ll1.5g / (kW · h), · 36 exhaust temperature down 2O ~ 68 ℃, and the outbreak of the pressure and turbocharger speed changes do not fire. Conditions for the load characteristics, mining Wo MPC booster engine,belstaff outlet, the fuel consumption in the entire load range down § ~ 9g / (kW.h ●, the outbreak of the pressure drop 0.9 ~ O.64MPa, speed of a turbocharger the rise. Beijing exhaust temperature at maximum load decreased by about 50 ℃} 2. Turbocharged diesel engine using MPC, \, improves the efficiency of the engine from 2.7 to 5.1%} 3. By hiding different turbine jet exit width of the comparison test loop that B = 0.0055m turbine nozzle is more suitable for the MPC by the local pressure system; 4. Turbocharged diesel engine using MPC to simplify the structure of the exhaust system, reducing the manufacturing cost of exhaust system to facilitate its installation on the engine} 5. Comparison of calculated and measured results show that the developed The MPC boundary model can reflect the characteristics of the gas flow MPC system for predicting the performance of MPC turbocharged diesel engine provides a section for improved design. |
